avr32/m68k/microblaze/nds32/nios2/openrisc/sh/sparc: fix do_bootm_linux Commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 broke bootm on avr32. It requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before calling it again with flag set to BOOTM_STATE_OS_GO. Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will require a complete refactoring later on.

Make sure that argv[] argument pointers are not modified. The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

Move lib_$ARCH directories to arch/$ARCH/lib Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
